The Raster Model

The raster model is a way of representing spatial data by dividing an area into a grid of many small squares called pixels. Each pixel has a value that describes a specific attribute, like color, temperature, or elevation. Think of it like a digital image or a map made up of tiny dots, where each dot’s color or shade conveys information about that location. This method is useful for capturing continuous data, such as satellite imagery or terrain models, providing detailed, pixel-by-pixel information across a landscape.
